Methodology

The City of Portland High Crash Network includes 30 streets; a composite of the top 20 high crash streets for driving, the top 20 for bicycling and the top 20 for walking.

The motor vehicle network includes the streets with the highest number of people killed or seriously injured (2004-2013). The bicycle and pedestrian networks include the streets with the highest number of crashes, regardless of severity, for people on bikes and walking, respectively (2004-2013).

While the aim of Vision Zero is to eliminate deadly and serious injury crashes, Portland included all crashes for people biking and walking because the difference between a minor injury and a serious injury to a person walking or biking is often random and circumstantial.
